What is computer aided design?Show answer
Computer aided design, or CAD, uses software to create accurate two and three dimensional models of a product.

Changes ripple through the model automatically, which makes iteration far faster than redrawing by hand. In the folio, CAD demonstrates professional communication and supports the development section.
What is computer aided manufacture?Show answer
Computer aided manufacture, or CAM, uses the digital model to control production equipment directly. Common CAM technologies include:
